I can't do this anymore

Carmella and Corey are getting married, and Carmella keeps demanding things from her sister Katinka while guilt tripping her by reminding her how she would never have met her husband Damian if it hadn't been for Carmella. Katinka can't take it anymore, and Damian has an idea. (Still no sign of Damian Priest on the list of names so I can't tag him to the story.)
